All, I've heard our MakerBot is a bit under powered now that we've installed a new higher power extruder assembly. We're looking for a 600W+ PC power supply to replace the one currently in our MakerBot. If you have one to donate or sell cheap, please let us know!

In theory if you just needed more current at 12V or similar you could hook them up in parallel and get greater current. In speaking with John, the problem is the maker bot uses the 24 (i think) pin output from a PC power supply, and this makes the brute force approach difficult. I think the current supply is 400W, it's possible a 500W supply would work. Or we could get a high current supply just for the extruder head heater, if we can isolate it's source and swap it out without having to mess with the rest of the circuitry.
